Abstract

An energy storage system, loads, and renewable energy sources all work together through power management in a DC microgrid, which is a small-scale power system. Over the past ten years, there has been a notable increase in both academic and industrial research on DC microgrids. When it comes to integration of renewable energy sources, control simplicity, efficiency, and dependability, DC microgrids outperform AC microgrids. Power generated from renewable sources is subject to variation, which can potentially result in undesirable variations. In the case of solar power generation, load demand variations lead to system instability and battery stress. High system variations have a negative effect on the DC microgrid's dependability and battery life. Using a hybrid energy storage system (HESS) at a DC microgrid that consists of batteries and a supercapacitor (SC) can help with this issue. In order to minimize battery loss and meet the generation demand mismatch, a new coordinated power control improves the power-sharing between batteries and SC. In this study, a standalone DC microgrid with a battery and supercapacitor is proposed as a means of optimizing capacity and minimizing loss. The MATLAB simulations show how these techniques greatly improve system performance overall and extend battery life.
